【摘要】：為了制備仔豬液體微生物發(fā)酵飼料,利用枯草芽孢桿菌和乳酸菌對(duì)仔豬全價(jià)飼料進(jìn)行發(fā)酵。通過(guò)單因素和正交試驗(yàn),以發(fā)酵后飼料中還原糖含量作為發(fā)酵條件的優(yōu)化指標(biāo)。得出最佳發(fā)酵條件為:總接種量4%其中芽孢菌與乳酸菌各為2%,料水重量體積(W/V)比為13.5,發(fā)酵溫度32~37℃。在條件37℃下發(fā)酵3 d,飼料含水量80%,還原糖含量達(dá)到2.17%提高10倍,乳酸含量3.4%,檸檬酸含量0.331%,丙酸含量0.130%,乳酸菌活菌數(shù)達(dá)到1010CFU/g。選取24頭6.45 kg左右的健康仔豬,分2個(gè)處理組,每個(gè)組3個(gè)重復(fù),對(duì)照組飼喂全價(jià)粉料,試驗(yàn)組飼喂添加50%發(fā)酵液態(tài)飼料。結(jié)果表明,與對(duì)照組相比,試驗(yàn)組平均日增重提高11.68%(P0.05),平均日采食量提高1.96%(P0.05),料肉比降低8.55%(P0.05),腹瀉率下降54.88%。
[Abstract]:In order to prepare liquid microorganism fermented feed for piglets, Bacillus subtilis and lactic acid bacteria were used to ferment the whole feed of piglets. The optimum fermentation conditions were obtained as follows: the total inoculation amount was 4%, the ratio of feed to water weight and W / V was 13.5, and the fermentation temperature was 32 ~ 37 鈩，
